A man trying to push his disabled car off the Chain of Rocks bridge was killed Wednesday when a tractor trailer could not avoid hitting him.

The tractor trailer struck the man around 5 am on the bridge, which carries Interstate 270 across the Mississippi River near the northern city-county border. The St. Louis police department said the truck driver attempted to swerve, but hit a median and caught on fire.

St. Louis police are investigating the accident. The highway remains closed and Missouri Department of Transportation officials say the highway may not re-open until late morning.
